Understanding Shape: Angles and Sides
March 1977 (vol. 26 no. 3)
pp. 236-242
L.S. Davis, Computer Science Center, University of Maryland
Methods of detecting the angles and sides of a simple closed curve are developed. These methods use approximations to the curve that have varying degrees of coarseness, and construct a hierarchy of angles and sides that describes the curve at any desired level of detail. The results can be used to obtain natural polygonal approximations to the curve.
Index Terms:
Pattern recognition, picture processing, shape analysis.
